A PDF version of Better Hearing Institute's (BHI) first installment in the MarkeTrak VIII research series titled " 25-year trends in the hearing health market" is now available for download.
The complete survey in zipfile (under Instruments) is also available for interested researchers. This zipfile contains the hearing loss screener and detailed seven-page legal size surveys for non-adopters and hearing aid owners. In addition, it contains a list of detailed panel demography variables. The screener went to an 80,000 household panel and the detailed surveys to a random sample of 5,500 non-adopters and 3,789 hearing aid owners.
